To aZwh/om t may concern;

' Be it known that I, GEORGE FRANKLIN 'WENTZ, a citizen of the UnitedStates, residf d istilling apparatus, especially of that type employedinthe distillation of water, though perhaps useful for other analogouspurposes.

The present invention relates more particularly to improvements in thesteam-generator, its construction, means ofsupport,

and themeans of supplying water thereto.

One of the features resides in mechanism which will permit theattachment of the genv erator to and its support upon a rsteam-boiler,

where it may be properly associated with the other elements' that go to`make up the distl-r.

ling apparatus as a whole. y

Another feature relates to novel automatic means for supplying water tothegenerator so that the said Water will eect the auto-l matic cleansingof the same.

Still another feature is the construction, arrangement, and combinationof theelements that constitute the generator as a whole, whereby adesirable and effectual manner of heating the water is obtained and .3.0

all the parts are accessible forthe purpose of repair, renewal, oradjustment.

n the drawings accompanying this specification, Figure 1 is a sideelevation of the improved distilling apparatus. Fig. 2 is a verticalsectional view, on an enlarged scale, through the generator. Fig. 3 is adetail horizontal sectional view through a portion of the same. Fig. 4is a side elevation of the oat employed, and Fig. 5 is a detailsectional view taken on the line 5 5 of` Fig. 3. Y I

Similar reference-numerals indicate corresponding parts in all theigures of the draw- Ings.

The'distilling apparatus is associated with an ordinary stand-boiler,(designated, 5,) alongside the lower portion of which is arranged acondenser-tank 6. A water-inlet pipe 7 has a branch connection 7 athrough a coupling 7b with the lower portion of the reservoir or boiler5, and said pipe leads, as shown at 7 C, to the bottom of the tank 6,and a Water-outlet pipe 8 extends from the topof the tank 6 and is incommunication with the top of the reservoir or boiler 5.' Brackets 9 arelocated against one side of the boiler and are secured thereto by aclamping-band 10, which surfices 28 in their upper sides. y heater isconnected with any suitable-source 'of gas-supply-as, forinstance, by atube 29,l

thecasing a slight distance, constituting an annular rib or bead 15,that forms a seat for the annular cylindrical wall 16 of the caslng.This casing-wall'l carries at its upper end a conical top 17, having acentral o penmg 1S, surrounded by a bead 19. Within the casing islocated the generator roper, which 1s in the form of a cylindricareceptacle 20,

. spacedfrom the walls of the casing to form an annular ilue 21; Thebottom 22 oiv this receptacle inclines downwardly to a centrallydisposeddepending sediment-trap tube 23, which tube extends through the centralopening 14:y of the casing-bottom 12 and 1s provided With a suitableturning valve 24. The top of the casing is in the form of a truncatedcone 25, disposed substantially parallel to the top 17 of the casing,but spaced threfrom, as shown. The receptacle'is suspended withinPatented March 20, 1806.

l rounds said boiler. The horizontal arms of the casing by means lofsuitable boltsor rivets 26, connecting the tops 17 and 25. As will. beseen by reference to FIg. 2, lthere 1s considerable space between thebottom of the receptacle and the bottom of the casmg, this space aordingsufiicient room for a suitable burner, shown in the presence instance inthe form of a -pair of concentric-ring tubes -27 surrounding thesediment-trap and having orlattached to an adjacent gas bracket 30.(Shown in Fig. 1.)

The top 25 is providedwlth a comparatively largecentrally-dlsposedhand-opening 31, surrounded by anupstandmgexteriorlythreaded boss 32. `Said hand-Opening 1s normally closed,however, by means of a {langecap 33, screwed upon the vboss and having ahand-wheel 34, by means of which it may be readily operated. This cap 1salso provided This burner or lCO IOS

with an annular internal flange 35, arranged to fit Within the boss32`and constituting means for holding suitable packlng, as 36,

which prevents the escape of steam through this joint. The cap isfurthermore provided with a centrally-disposed upstanding nipple 37, towhich is coupled, by means of a sleeve 38, one end of a steami e 39,said steampipe being of considerably ess diameter than the diameter ofthe hand opening. The

-steam-pipe 39 extends through the condenser-tank 6 and terminates in awater-discharge pipe 40, which may be introduced into a suitablereceiving vessel 4l. An air purier and mixer 42 is located in the pipe39.

Means are employed for automatically supplying water to the generator.As illustrated in Fig. 1, a water-supply pipe 43 leads from theoutlet-pipe 8 between the condenser-tank and the reservoir or boiler 5to the lower portion of the generator-receptacle 20. The passage-waythrough this pipe can be closed by means of a turning valve 44, Fig. l,so that, if desired, the supply of water can be entirely cut off. Anautomatically-operated valve is also provided for this purpose and isfully illustrated in Fig. 2. The pipe 43 terminates in ahorizontally-disposed nozzle, (designated as a whole by thereference-numeral 45,) the inner end of which is in the form of a cap orhead 45a, that projects into the receptacle 22. This nozzle contains avalve-seat 46, with which coacts a valve 47, arranged within the nozzle.The valve op ens against the pressure of the water, and one end thereofcoacts with the valve-seat, the opposite end, or, in other words, thatopposed to the How of the water, being made conical, as shown at 48, forthe purpose of offering as little resistance as possible to such How.The valve carries a stem 49, that projects beyond the inner end of thenozzle into the receptacle, where it is pivoted, as shown at 50, to thedepending short arm of a bellcrank lever, that is pivoted to a bracket52, forming a part of the inner end of said nozzle.` Another arm 53 ofthis bell-crank lever extends transversely of the receptacle, and on itsfree end is mounted a cylindrical iioat 54. An ear 55 is attached tothis float and is adjustably mounted on the arm 53, being normally heldagainst movement, however, by a set-screw 56. On the outer end of thearm 53 are secured suitable counterweights 57, held in place by a cotteror split key 5S. Itis to be noted by reference to Figs. 2, 3, and 5 thatthe inner end of' the nozzle is closed with the exception of the smallopening in the cap or head, through which the valve-stem 49 extends andiits as snugly as is desirable to prevent the passage of water thereto,such passage, moreover, being prohibited by a washer 59, locatedupon thestem and movable into engagement with the end wall of the nozzle whenthe float is depressed. The outlet for the water is through a lateraldischarge-oriice 60, that extends in a plane perpendicular to the stemand is inclined downwardly, so as to form an angle with the horizontaland with the bottom 22, which orifice thus projects the water downwardlyagainst the bottom 22 ol' the receptacle and at an inclination to saidbottom for the purpose hereinafter pointed out.

The operation of the apparatus isas follows: Assuming that the boiler orreservoir 5 is supplied with water under pressure, it will be evidentthat the condenser-tank 6 will likewise be iilled and that water flowingthrough the supply-pipe 43 will enter the generator-receptacle 20 untilthe iioat 34 rises sufficiently to close the valve 47. lf heat is nowapplied to the receptacle `from the burner, the water therein will beheated and brought to a boil. Particular attention is invited to Fig. 2,which shows the circulation of such water. Instead of an outwardcirculation, as is ordinarily the case with a receptacle, the heat beingsupplied not only to the bottom, but to the sides, will cause an upwardand inward circulation at said sides and a downward circulation at thecenter. The effect is that the sediment will to a great extent bedeposited at the center, and thus `lind its way into the sedimenttrap23. The steam generated will of course iind its way through the pipe 39and be condensed within the tank 6, the condensed water iinding anoutlet into the vessel 41. This condensation of the steam will of courseheat the water in the tank 6, which will enter the top of the boiler orreservoir 5. As the level of the water within the generator-receptaclefalls, due to the carrying ofi' of the steam, the iioat will fall withit, and consequently a fresh supply ci" water will be introduced throughthe supply-pipe 43. Now, as this supply-pipe is connected with theoutletpipe 8 for the heated water, vit will be evident that heated waterwill be furnished to the steam-generator. Moreover, this water will beprojected downwardly and at an inclination against the bottom 22 of thereceptacle, causing a gyratory movement of the body of water within thereceptacle, which movement thoroughly cleanses and scours the bottom andgradually works the sediment deposited thereon to the trap 23, whence itmay be drawn. Thus to thoroughly cleanse the receptacle, it is onlynecessary to open the valve ci the sediment-trap and permit the water tollow therefrom for some time. When said trap 24 is opened, the watercontained in the receptacle of course passes out through said trap, andthe loat, sinking with the level oi the water, opens the valve 47 to itsfullest extent. The washer 59, secured to the outer end of thevalve-stem 49, thereupon abuts against the end 45 of the nozzle,consequently closing the opening therethrough, and thus securing thefull force of the escaping water through the oriiice 60. This washer,furthermore, constitutes a stop that limits the downward movement of thei'loat and arm in order to IOO IOS

TIO

. prevent its striking the bottom of the receptacle.

It will be evident that this arrangement has many advantages, as itsecures puriiied water practically Without the necessity ofthe attentionof an operator. The supply of water to the generator being automatic,there is no danger of burning outthe elements, and this automatic supplypractically constitutes the means for keeping the generator in asanitary condition; The entire structure can be readily supported uponan ordinary standboiler and attached to any convenient source ofgas-supply. Moreover', access can be readily gained to any or all of thearts. The casing is so constructed that the urner may be readilyreached, and by removing the cap l33 the hand maybe passed into thereceptacle and by disassociating the parts therein the float and valveconnections may be easily.'

removed.

From the foregoing it is thought that the construction, operation, andmany' advan- 'tages .of the herein-described invention will be apparentto those skilled in the art without further description, and it will beunderstood that various changes in the size,

shape, proportion, and minor details of construction may beresort'ed towithout de arting from 4the spirit or sacrificing any o the advantagesof the invention.` f
